Denial of a speedy trial

In jurisprudence, denial of a speedy trial is a procedural defense via which, a defendant argues that they should not be held criminally liable for actionss which broke the law, because the criminal justice system placed them in prison for an "unreasonable" length of time (prior to any trial). In the US, this defense is based upon the 6th Constitutional Amendment; which states: "In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial..." In many jurisdictions, if a defendant remains imprisoned for more than 90-120 days, before a trial occurs, all charges are automatically dropped.
